🔩 Flange Nut – Integrated Washer Locking Nut | Neo Fasteners
Flange Nuts are hexagonal nuts with a wide, built-in washer-like flange at the base. This integrated flange distributes pressure over a wider area and helps prevent loosening due to vibration. Ideal for applications requiring even load distribution and secure fastening without a separate washer.
At Neo Fasteners, we supply a complete range of standard and serrated flange nuts in multiple thread sizes, materials, and finishes, compliant with DIN 6923, ISO 4161, ASTM, and IS standards.
🛠️ Key Features
- Hexagonal nut with integrated flange base
- Reduces need for separate washers
- Prevents damage to mating surface
- Optional serrations provide self-locking ability
- Excellent for automotive, assembly lines, machinery, and construction
